rowDEiE-CUTTING Meel-TINE.

ToaZZ fwkom t may concern I Bre 1t known that I, JAMES'P. ENGIJSH, a citizen of the United States, residing'at Parlin, county of Middlesex, and. State of l New Jersey, and I, HARRY Gom, a citizen of Russia, residing atJersey City, county of Hudson, and State of New Jersey, have invented lcertain new and useful Improvements in Powder-Cutting Machines, of which the following is' aspecification. This-.invention relates to improvements in means for cutting smokeless owder or like semi-plastics into definite engths as the same is extruded from a reservoir or the powder makin machine direct.

The principal o I' to provide a mechanism which may be cnovel construction and combination of parts l showing a modified form of cani.`v Fig-.8 is an end view thereof,- and A further vobject lis `to provide whereby the length and weight of each stick curately adjusted to cut off predetermined lengths of the powder rods 1n a safe andA expeditious manner. v

means can be accurately adjusted,'the machine being capable of working upon v a plurality of the extruded rods'simultaneously.

- This and other objects are attained bythe hereinafter described and shown in the accompanying drawings, forming 'a material part of this disclosure, and in whichz- Fi re 1 is a fragmentar vertical sectiona view taken substantia on the center line of a machine made 1n accordance parts being shown in another osition.

Fig. 3 is a transverse sectiona view'taken on line 3-3 of Fig. 1.

Fig. 4 is a partial plan 'view' looking 40 downward on theparts shown in Fig. 1.

Fig. 5 is a side elevational view showing. -the preferred form of operating pamhpsed in the mechanism.

Fig; 6-.is an end view thereof. Fig. v7 'is a similar sidel elevational view Fig.. 9 is afragmentary view indicating the roller used in connection with the cam lshown in Figs. 7 and 8. In Fig. 1 ofthe drawin the numeral 14, designates the front en orheadof a stationary'cylinder, in which operates a plunger .15, compressing the. powder, when in a semi-plastic condition, forcin the same.

outwardly'through a plurality o openings ject of the invention is Specification oi' Letters Patent. Patented Sept, 24, 191.8, Application inea April 17, 191s.- seriai No. 229,050.

arms 22 is a circular block 23, and journaled` axially'therein is va spindle 24, driven by a pulley 25, rotated by a belt 26 from any convenient source of power.

Formed in the innerend of the block 23 is a circular openin 28, and extending lnto the opening are a p urality of rectangular recesses 30 partially covered at their ends by a plate 31 containing a central opening 32 .equivalent in diameter to the circular recesses 30, are opposed slots 34.

Slidable inthe recesses-30 are'carri'ages comprised of blocks' 36 to which are attached kopening 28,-and formedinthsides of the square blocks 37 containing cylindrical l openings 38, which are alined in register with the openings 16 formed in the head 14, thus permittingv the extruded powder sticks to extend directly through.

l The opposite ends 40 of the carriages.

have fixed in their guter surfaces pins 41, surrounded by heli al coiled compression springs 42, adjustable by screws 43, the

heads ofjwhich extend outwardl beyond the block 23. Mounted to slide transversel the recesses 30, upon the inner sides o the elements 40, are blocks 45, carrying slidable pinsj46 surrounded by coiled .compression springs 47, opposed to the screws 48, which abut against the stop the pins 46' are secured.

Thus the lpowder sticks extruded through 'the head 14, and passing through the cylindrical guides 38, make contact with the faces ofthe stop plates 50, forcing the s outwardly.- Slidable transversely cari-ia upon t e inner surfaces of the carriage bloc passing through therecesses 30, into the central opening 28 and are pressed inward by the coiled compression springs 54, 'which Engaged-by the screws 55,'to the blocks plates 50 in. which lelements36, are other'blocks 52, the same.

52 are cutters 56, the same'bemg adapted to pass transversely across they cylindrical openings 38, outlets 57 being provided opposite to the cutters, so that a small portlon of the powder, ters may be extruded.

pressed forward by thev cut- Formed in the inner faces of' the blocks 52, are conical 'openings 60, terminating in lcylindrical passages 61 which extend comwithdrawn from Contact with the end ci the,

powder stick 20, as the cutters 64,- are transversed thereacross, severing the same, permittin the blocks to drop into a container suitab y arranged below the apparatus.

Extending radially inward from the lower v ends of the sliding blocks 52, are pairs oi pins 72, pressed toward the center, due to the edect ci' the springs 54, and restin upon the extending end 75 of a cam' rigi gaged with the spindle 24, the cam aving a main cylindrical part 76 and a single raised oval loop 77, containing a helical groove 78', startin upon the surface 'Z5 at zero and adapted to engage between the pins 72 at such time as a sticlr of powder has moved the vblock element outwardly into position for engagement, so that the starting point of the cam will enter-between the pins. The angularity or pitch of the cam slot is made in' accordance with the delivery of the powder, so that the carriagescarrying the cylindrical guides and cutters are moved outwardly toward the front of the machine simultaneously with the advancement oi the powder sticks.

ln the form shown in Figs. 7 to 9 inclu# s1ve, a slightly different shape ocan'i is used, the saine having a single raised ele nient 80 containing a slot 8l, adapted to engage with a roller 82 mounted upon the block 52 in an obvious manner.

ln all other respects the construction is as before described ln operatiom-the spindle 2e being actuated, and the powder sticks 2O expelled 'from the"head ifi, due to the pressure oi the plunger 15, the powder will be extruded in the torni o' cylindrical rods, passing readily into the openings 38 until contact is made with the stop plate, moving the carriage along the slideway-recesses 30, toward the outer end of the machine until the cam'has action oi'.E the lever 6d and should the severed portions'oi the owder sticks4 adhere to the tubular uides tney will be removed by contact wit ig il,

the stop plates as indicated in Lerasve It is to be noticed that all oi the several operations are continuous and. automatic and that ad'ustment ofthe stop plate 50 may be accuratel made so that the weight of the powder Stich cut oli may be adjusted'to a nicety. Y

lt will also be apparent, that due to the several openings through which the powder is extruded, that the work is performed in an expeditious manner, and with entire safety to the operator. l

Having thus `described our invention what we claim as new and desire to secureby Letters Patent, is-v 1. ln a powder cutting machine the combination with a head having ined der in a semi-plastic condition, and means for projecting thev powder therethrough, of stop plates enga eable with the extruded ends of the pow er sticks, a carriage upon which said plates are mounted, a cutter fixed transversely of said guides, a block vupon which said guide is mounted, a rotating cam,

means formed with said block adapted to maire contact with said cano, and ax lever hinged between said block and said stop plate whereby said cutter and said stop plate are moved simultaneously in opposite directions.
